The Y-12 facility has been in operation since 1943 as part of the Manhattan Project, and today is responsible for both the production and maintenance of all uranium parts for the entire US nuclear weapons arsenal. Over the years, the facility has also been the target of nonviolent anti-nuclear protests.

Now, a jury in Tennessee has charged the three protesters with sabotaging the plant, with a second charge of damaging federal property.

“The shortcomings in security at one of the most dangerous places on the planet have embarrassed a lot of people,” defense lawyer Francis Lloyd said.

“You’re looking at three scapegoats behind me,” he added

Defense attorneys also noted that, once the three refused to plead guilty to trespassing, which carries a maximum sentence of 10 years’ imprisonment, the prosecution introduced the charge of sabotage, which carries a maximum prison term of twenty years. They believed the higher charge should have been dismissed.

According to the Associated Press, which provided details of the court proceedings, the three activists have no remorse for their actions, and were pleased to have reached one of the most secure areas of the facility.

Prosecutor Jeff Theodore noted that the trio’s fate could have been far worse, as that area of the facility allowed guards to use deadly force.

“They’re lucky, and thank goodness they’re alive, because they went into the lethal zone,” said Theodore.

The three defendants spent two hours inside Y-12, during which time they hung banners, cut through security fences, strung crime-scene tape and sprayed “baby bottles full of human blood” on the exterior portion of the facility.

Boertje-Obed, who is a house painter from Duluth, Minnesota, explained why they sprayed the blood.

“The reason for the baby bottles was to represent that the blood of children is spilled by these weapons,” he said.

While inside the most secure portion of the facility, the three activists managed to hammer off what is described as a “small chunk” of the Highly Enriched Uranium Materials Facility.

During cross examination, Sister Rice stated that she wished she had not waited so long to stage a protest within the plant.

“My regret was I waited 70 years,” she said.”It is manufacturing which can only cause death.”

Prosecutors argued that the breach of security was serious, and caused the plant to shut down for two weeks as security staff were re-trained and defense contractors replaced.

Meanwhile, federal officials maintain that there was never any danger of the three activists reaching materials that could be detonated or used to construct an improvised bomb.
